The sampling and processing is done in a separate thread. The GUI shows the detected note, the required freq, the detected freq, a graphical indication of whether the detected freq is above or below the required one and a Tune Up / Down message.

The program prevents suspend and screen dimming on FSO / SHR.

The program automatically selects the correct state file. It also prevents suspend and screen dimming on FSO / SHR.

Guitartune does a Fast Fourier Transform followed by a Harmonic Product Spectrum to calculate the fundamental frequency of sampled audio data.
